The cultivation of what would become canola began in the Canadian Prairies during World War II, primarily to produce lubricants for naval vessels. After the war, efforts to transition this crop into a food source faced significant hurdles. The original rapeseed contained high levels of erucic acid, a compound linked to health concerns, and glucosinolates, which imparted a pungent flavour and made the meal undesirable for animal feed. These inherent drawbacks severely limited its widespread adoption in the human and animal food chains, despite its excellent adaptability to the harsh prairie climate. This situation highlighted the necessity for substantial agricultural innovation.

A pivotal moment arrived in the 1960s when dedicated Canadian plant breeders, notably Baldur Stefansson and Keith Downey, embarked on an ambitious program to refine rapeseed. Utilizing traditional cross-breeding techniques, they meticulously developed new varieties specifically engineered to possess significantly reduced levels of erucic acid and glucosinolates. This painstaking multi-generational process led to the creation of "double-low" varieties, yielding an oil that was safe and palatable for human consumption, and a protein-rich meal suitable for livestock, fundamentally altering the crop's potential.

To clearly differentiate the improved oil from its problematic predecessor, a new identifier was introduced in 1978: "Canola." This portmanteau, merging "Canada" with "ola" (signifying oil, low acid), was a strategic marketing move. It aimed to shed the negative perceptions associated with traditional rapeseed and establish a distinct, positive brand identity. Early promotional campaigns emphasized its nutritional advantages, particularly its low saturated fat content and beneficial fatty acid profile, successfully positioning it as a healthy cooking oil in both domestic and international markets, thereby securing its commercial viability.

The successful development and market penetration of canola oil brought about a profound economic transformation for Canada. What started as a specialized crop evolved into one of the nation's most valuable agricultural exports, significantly bolstering the economies of the prairie provinces. Canada has solidified its position as a global leader in both the cultivation and export of canola, with the oil becoming a ubiquitous ingredient in food products worldwide. This versatile commodity now contributes billions of dollars annually to the Canadian gross domestic product and sustains numerous jobs across the agricultural and processing sectors.
